Magnetic nail file and method of fabricating same

ABSTRACT

The nail file includes a magnetized material layer and an abrasive surface. The magnetized material may be the base of a metal nail file or a magnetized layer in an emery board. In the latter case, the abrasive surface may be proximate one or both sides of the magnetized layer. A base layer may be interposed between the magnetized layer and abrasive surface.

DESCRIPTION OR PRIOR ART INCLUDING INFORMATION DISCLOSED UNDER 37 CFR 1.97 AND 1.98

Finger nail files made of metal or of nonmetallic materials such as cardboard or wood, the latter commonly known as “emery boards” because of the use of emery minerals to form the abrasive surface, are widely known and used. However, none have been formed of magnetic material so that they can be removably attached to a metal surface and therefore be readily accessible when needed.

For example, finger nails are often broken in the office during the course of inserting documents into or retrieving documents from a metal file cabinet, or at home while working in the kitchen. It would be extremely handy to have a finger nail file removably attached to the exterior surface of the file cabinet draw or the outside of the refrigerator door in such instances. However, conventional finger nail files do not have that capability.

Further, emery boards provide a heretofore unused medium for displaying graphics for decorative purposes. They also constitute an excellent means for carrying advertising graphics and/or text, such as company logos, making them ideal for use as promotional items because of their low cost. Being able to removably attach such decorative or advertising emery boards to metallic surfaces would considerably enhance their utility.

Accordingly, there appears to be a real need for a magnetic nail file and particularly for a magnetic emery board type nail file that is decorative or promotional in nature.

It is therefore, a prime object of the present invention to provide a magnetic nail file.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board formed of a magnetic layer and an abrasive layer.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board formed of a magnetic layer and an abrasive layer, with a base layer interposed therebetween.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board formed of a magnetic layer interposed between abrasive layers.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board which includes a decorative surface.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board which includes a surface carrying advertising graphics and/or text.

It is another object of the present invention to provide a magnetic nail file in the form of an emery board which can be used as a promotional item.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates the metallic embodiment of the present invention, generally designated A. As seen in FIG. 1, nail file A consists of a base 10, formed of a metal that has been magnetized. Base 10 preferably has an elongated, generally rectangular configuration with rounded ends. Base 10 has upper and lower surfaces 12, 14. One or both of the surfaces 12, 14 are provided with an abrasive surface formed of plurality of closely spaced, fine teeth 16, as is customary for a conventional metallic nail file.

FIGS. 2 and 3 illustrate a first version of the emery board type embodiment of the present invention, generally designated B. As seen in the drawings, nail file B includes three layers. Layer 20 consists in whole or in part of magnetic material, such as magnetized metal. Layer 22 includes an abrasive surface. A base layer 26 is interposed between layers 20 and 22 to provide strength and rigidity. Layers 20, 22 and 26 are attached to each other by an adhesive in order to form a multi-layer unit which is the die cut to the desired size and shape.

The abrasive surface of layer 22 may be formed of grit particles 24 on a substrate 28. Particles 24 may consist of or include any emery mineral, such as corundum, garnet, flint or glass. However, it is preferable that particles 24 be made of aluminum oxide or silicon carbide.

In one preferred method of forming the abrasive surface, particles 24 are embedded in latex. The latex embedded particles are coated onto a woven fabric that is then electostatically charged to cause the particles to stand up such that they “wave” back and forth in the latex. Particles 24 preferably have a grit range of from 60 to 12,000.

Substrate 28 may be formed of paper, such as a waterproof paper that is resin coated or impregnated. However, substrate 28 also can be formed of “dry” craft paper. Either type of substrate can be imprinted using a dye sublimation transfer process, silk screening, or pad printing. If craft paper is used, it can be printed and then coated.

Alternatively, substrate 28 can be formed of a thin film. Suitable films for this purpose are transparent, translucent or colored polyester or DuPont Mylar.

The layers are attached together using a thin layer of adhesive. The adhesive used to attach the layers may be any acrylic or rubber based, coated or pressure sensitive adhesive. However, other conventional attaching methods may be used as well.

Base layer 26 can be made of a foam material, which may have a thickness in the range of from 1/32^(nd) to ¼ inch. Alternatively, layer 26 could be made of high impact polystyrene that is about 1/16 inches thick or of a wood veneer with a thickness range from 1/24to 1/20 inches. Other possibilities include fiberglass and decorated paper.

Base layer 26 could also consist of two or more attached sublayers. Those sublayers could be formed of any of the previously mentioned materials, or of a combination thereof.

Instead of printing or decorating the abrasive substrate of layer 22, the substrate could be formed of transparent or translucent film and the surface of layer 26 facing layer 22 could be imprinted with graphics and/or text or otherwise decorated.

FIG. 4 illustrates a second version of the emery board type embodiment of the present invention, generally designated C. Nail file C includes a layer 20′ made in whole or in part of a magnetized material. Layer 20′ is interposed between two abrasive layers 22′, each having a surface formed of abrasive particles 24′ on a substrate 28′. The substrate 28′ in each of the layers 22′ may be imprinted or decorated. Thus, nail file C will have abrasive surfaces on both sides, one or both of which may be imprinted and/or decorated.

It will now be appreciated that the present invention relates to a magnetic nail file, which may be of the metallic or emery board type. One or both sides of the file are provided with abrasive surfaces. One or both of the sides of the file may be imprinted with graphic and/or text materials or decorated in other ways. The metallic embodiment is made in whole or in part of magnetized metal that has an abrasive surface on one or both sides. The emery board type embodiment consists of multiple layers, at least one of which includes magnetized material and one of which has an abrasive surface. In one version, a base layer is interposed between the layer with the abrasive surface and the magnetized material layer. In a second version, the magnetic layer is interposed between layers with abrasive surfaces.

While only a limited number of preferred embodiments of the present invention have been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
